Okay could you please post the fu= ll defaults=2Esh then as I assume this to configure sqm=2E
Also the outp= ut of
tc -s qdisc
tc -d qdisc
Would be interesting=2E

Hi Y,

when you =
shape for an ATM link you absolutely nned to set the
linklayer to ATM=2E=
 If you use openwrt why don't you post the contents
of "cat /etc/config/=
sqm"
here and we can go over it line by line?

Hi , Dave
Thank you for your reply=2E

I should show you tc=

My connection is PPPoA via ethernet=2E PC connects =

####stab linklayer atm overhead -4

I add=
 PPPoA overhead 10 + Ethernet overhead -14 =3D -4
But, settled Bandwith =

I should shape more?
